UX Design: Create wireframes for domain groups

[Katherine-Osos]

Story

As an org admin
I want to assign my domains to logical groups
so that I can easily filter for them in the registrar

Acceptance Criteria

• Review similar functionality available in other registrars.
• Design wireframes that allow users to:
  • Create their own groups
  • Add/remove domains to a group
  • View the groups associated with each domain

Additional Context

• View Slack thread that references some examples from other registrars.
• Post MVP, the groups may be used to assign managers to a set of domains, specify nuanced permissions, or set defaults to a set of domains.
• "Domain groups" is used in this ticket as placeholder and may not be the term we use.
  • We still need to determine what to call this feature. Groups, tags, labels, categories, and folders are a few of the options we've discussed.
